CLOSURE FOR JARS AND OTHER RECEPTACLES.

Application filed September 18, 1928. Serial No. 663,340.

The invention relates to jars and like receptacles, and it resides in a jar and a novel closure therefor comprising an outer cap hermetically sealing the jar and an inn'er'cap seated on a shoulder formed on the jar suitably below the lip thereof and concealed by said outer cap, said inner cap being of (llSk outline and engaging [the inner side walls of thejar near the mouth thereof with sprin efi'ect and being integrally formed at one e go with an inwardly extending member which may be used as a finger-hold in withdrawing the inner cap from the jar. The inner cap' is for use, more particularly, in N resealin the jar after the outer cap has been removed and portions of-the contents of the jar are from time to time consumed. The invention has been designed more particularly for use in preparing food products for and shipping them into hot climates, in some of which insects are so very numerous that reat care is required in excluding them 0111 food products. The outer cap affords an eflectual seal to preserve the food during transit and while held in stock and the inner cap provides convenient means for rescaling the jar as the contents thereof are from time to time consumed.

The invention will be' fully understood from the detailed description hereinafter presented, reference being had to the accom panying drawings, in which: a

Fig. 1 is a central vertical section, on an enlarged scale, of the neck portion of a jar and closure thereon embodying my invention;

Fig. 2 is a top plan view the outer cap omitted;

. Fig. 3 is-a detached central vertical section of the inner cap or reseal feature of the invention, and. I

Fig. 4 1s a detached perspective view of a modified form of inner or reseal cap embodying. my invention. i

- I In the drawings 10 designates a jar having within its neck and suitably below the lip around the mouth of the jar, an annular horizontal shoulder 11 above which the neck has plain vertical walls 12. The neck has plain outer walls 13 which afi'ord broad sealing surfaces. v The inner cap, numbered 14, may be made of thin aluminum and is of dish-shape having a flat bottom and downwardly and inwardly inclined rim or side portions 15 formedat of the same, with one side with a finger or 16 which ner mally will be bent inwardly over the cap, as 7 shown. The inner cap 14 is adapted to seat upon'the shoulder 11 and when forced to position thereupon the sides 15 of the cap are crowded downwardlyagainst the walls 12 of the jar-neck 17, and thereby said sides are sprung inwardly and made to grip the walls 12 with a spring tension which serves to hold the cap firmly on the shoulder 11 and in secure portion. The cap 14 tightly fits within the neck 17 and as a reseal will exclude insects, dust and the like from the contents ofthe jar. When it is desired to withdraw the inner cap 14, after the outer cap 18 has been removed, the finger or tab 16 will be taken hold of and a pull on this finger or tab, the same being at one edge of the cap, will dislodge the cap. The cap 14 may be repeatedly'used as a reseal.

The outer cap ,18 has a top and a depending-skirt or flange 19 which is an: grooved to receive .a asket 20, said gs being firmly held against the side walls 13 of the jar by said skirt or flange and securely sealing the jar. The cap 18 may he formed ofaluminum and said cap and the gasket 20 m preferably, though not necessarily, the cap and gasket disclosed in Let ers Patent No. 1,353,397 issued to Alfred Ingram and Harry Ingram on Se tember 21, 1920.

The outer ca 18 is relie upon to preserve the contents 0 the jar a ainst deterioration during shipment and w ile the goods are held in stock. When the jar is in the hands of the consumer and is to be opened, the cap 18 will, as usual, be removed, and thereupon the inner cap 14. will be withdrawn, in the manner herembefore described, leaving the Y jar open. After a portion of the contents of the jar has been removed the jar will be rescaled b the return thereto of the cap 14, said ca t en protecting the remaining contents o the jar. The cap 14 is intended for reseal purposes and may be used repeatedly.

In Fig. 4 I illustrate modified construction of inner cap and the same is numbered '21 and consists of a disk 22 and a series of upwardly extending spring fingers "23, one of which is formed with the inwardly bent finger-piece or tab 24 corresponding with the finger or tab 16 of Fig. 3. The fingers 23 normally incline downwardly and inwardly and represent sections of the rim portions 15 of the inner cap 14 and are used for precisely the same purpose as said por- V tions 15 The inner cap '14 or 21, does not project above the lip at the mouth of the jar, and hence does not interfere with the proper application of the cap 18, with which the inner cap cooperates in protecting the contents of the jar. v

, What I claim as my invention and desire to secure" by Letters Patent, is: a 1. A jar or the like having an annular shoulder Within its neck and below the mouth of the jar and outer side surfaces at said mouth, and a closure therefor comprising an inner cap adapted to seat on said shoulder and having upwardly extending side portions to engage the inner sides of said neck above said shoulder with a spring tension, and an outer cap having a depending annularly grooved skirt holding a gasket firmly engaging said outer side surfaces of and hermetically sealing the jar, said inner cap being in one integral piece of resilient sheet material and having formed on the edge thereof an inturned finger-piece to facilitate the withdrawal of the cap.

2. A jar or the like having an annular shoulder within the neck and below the mouth of the jar, and a closure therefor comprising an outer cap hermetically sealing and an inner reseal cap adapted to seat on said shoulder and having upwardly extending side'portions to engage the inner sides of said neck above said shoulder with a spring tension, said inner cap being in one integral piece of resilient sheet material and having formed on the edge thereof an inturned finger-piece to facilitate the withdrawal of the cap. 7
